Yes. CH340G used for programming via the bootloader (using stcgal), and
to be used later to get the serial data. Worked for me on the
STC89C52RC. The STC8A8K64S4A12
Is there anything connected (e.g. a USB connector for programming) to P3.0
and P3.1? Both IAP15W4K58S4 and STC8A8K64S4A12 seem to be able to switch
these pins to some kind of USB mode for programming. For STC8A8K64S4A12 the
manual mentions P3.2 needs to be at low level at powerup for this to work.
